Can someone use Pebble and Twine against me?

Hi folks! Those Pebble smart watch and Twine sensor from Kickstarter are cool things to have but can they be used in the wrong way by anybody?

According to The Guardian (link is external), “When engineers began monitoring traffic on a two-lane road outside of London and comparing traffic on the roads of the city of London, they discovered 10 breakers per day. roads. This would result in thousands of users across the country, given the amount of traffic on the road.

Twine is a small box with bunch of sensors and WiFi connectivity inside. Pebble smart watch uses Bluetooth connection to get data from your iPhone or Android smartphone. Their work lies in this: Twine sensor receives a signal and sends a message over its WiFi connection to your smartphone and Pebble smart watch reads it and using Bluetooth connection shows it on its screen.

Despite the obvious usefulness of this technological symbiosis (for example, you can place Twine sensor at your door and get a message when someone is knocking on it) Twine and Pebble might also be misused in the similar way (the bad guy can place Twine sensor at your door and know when you leave your house or come back home). But you can block Twine and Pebble wireless connections and prevent any bad consequences of evil people’s deeds.

GPS jammers create a 500m “bubble” around a vehicle when plugged into the cigarette lighter. In this area, the GPS does not work, the security technology of the aircraft can be affected and the tracking systems stolen cars location. Truck drivers and taxis who are monitored to prevent them from driving for long hours illegally can also use them to avoid detection, although the report does not specify how a GPS records the location rather than the time spent driving .
